Product Description
Centrifugal extractor used in environmental protection industry widely, used multistage extraction, back extraction etc. for phenolic wastewater treatment, ships oily water separation, underground water separation and purification and so on.
In this case, we mainly introduce phenolic wastewater treatment:
Phenolic compounds are important chemical raw material or intermediates, which are also produced by many mining enterprises.Direct emissions wasterwater containing phenol, if a great of harm to people, aquatic life, agricultural, phenolic wasterwater in water pollution control in our country is listed as the key to solve one of the poisonous and harmful wastewater, it must remove phenol, and reach the requirements of environment protection, and then discharge.
Solvent extraction method has been a good effect and low cost treatment method.
The process is: Adapted the agent which could dissolve pollutants but undissolve water, made it and wastewater in full mixing, used its different distribution ratio in water and solvent to separate and extract pollutants, it is a kind of wastewater purification method. Extraction agent with material that need to be extracted go process back extraction with back extraction agent, to recover valuable products, and the extraction agent is recycled and reused.
Zhengzhou tianyi extraction technology co.,ltd bring out CWL-M series centrifugal extractor aimed to phenolic wastewater, and turning it into treasure. This series extractor is our the 4th product with our independent intellectual property rights, and patent number: ZL2014205865573. Under the same handling capacity, this series of machine energy consumption is 10%~30% of traditional annular type. At the same time, and it has short duration, split phase velocity, high extraction rate, save cost and solvent could be recycled and reused.
Other name of product: high concentrated organic wastewater treatment centrifugal extractor, phenol wastewater treatment centrifugal extractor, coking wastewater centrifugal extractor
Processing capacity: 1000-150000 L/H
Product category: multistage counter current extraction device, multistage cross current extraction device, single stage centrifugal extractor.
Application fields: such as coking industrial gasworks, coking plant, oil refinery, gas generation station, kerosene plant in coal oil plant, forestry plant, the factory that regard phenol as raw material, which produce resin, plastic synthetic fibre, dye, medicine, spice, pesticide, food additives, fibreglass, paint, sanitizer, flotation agent and so on.
Customization or not: Yes
If supply small test or pilot-plant test: Yes
Working principle
1.Mixing and mass transfer process:
Light and heavy liquor enter in the annulus mixed zone proportionally and from two different feed pipe orifice respectively, which formed by bowl and shell, with the help of bowl's rotation, the two phases through turbine disc and impeller mixing and dispersing quickly, after mass transfer completely, to finish mass transfer process.
2.Two phases separation process
With the eddy-current disc help, mixture enter in bowl, at the compartment formed by board, the mixture is quickly synchronized with the bowl, under the action of centrifugal force, the larger density liquor moving away from the bowl center to the wall gradually in the upward flow; and the small density liquor doing the opposite, after clarification, two liquids enter into collection chamber with their own weir plate respectively, and drawn out by tigella, to finish the separation process.
Charateristic:
1. Obvious separation effect with centrifugal force, big processing capacity;
2. Short contact time, to save extraction agent.
3. High mass transfer and stage efficiency, convenient to start up or stop, it can not break balance when stop.
4. Cover small area, low comprehensive invest.
5. High adaptability, high flexibility, it could batch operation, single operation, continuous and counter current operation, there is no need to add stage pump.
Technology Process:
Extraction process: Phenolic wastewater and extractant enter in centrifugal extractor in proportion at the same time, after 2-3 stages extraction, wastewater was discharged;
Back extraction process: Extractant contained phenol( load organic phase) enter in back extractor, at the same time, alkali liquid enter in proportion, after 2-3stages back extraction, alkali washing, and the extractant could be recycling. Sodium phenolate liquid formed after back extraction could be recycling.
Successful case
Naphthalene sulfonate organic wastewater treatment with centrifugal extraction method.
Project context
Nephthalene sulfonate organic wastewater from one chemical plant need to treat, most of the wastewater with large density, high toxicity, deep color and complex ingredient, they are harm to human and environment. It is hard to remove the impurity with common oxidation style or biochemical process, cause that the organic structure of the wastewater is stable, while centrifugal extraction method can achieve a better effect.
Extraction technology: Centrifugal extraction
Extraction extractant: Complexation extractant composited of amine extractant and kerosene was chosen by experiment.
Extraction Process:
Under a certain of experiment condition, Used our cwl-m series centrifugal extractor to extract. The result showed that the remove rate of COD was up to 96%, and then used 20% alkali solute as back extractant for load organic phase to back extract, it found that regeneration extractant after back extraction could be reused many times without affection effect.
